Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.
